Question: How to Load scripts,styles and recatcha v3 only when needed

This was used to work, but the filters does not work anymore.

Ok, that means the filters won’t work anymore in the future and that I can remove it and only use the new code posted today?

function deregister_javascript() {
	if (!is_page('contact')) {
		wp_deregister_script('contact-form-7'); // Contact form 7
		wp_deregister_script('google-recaptcha'); // Contact form 7
	}
}

add_action('wp_print_scripts', 'deregister_javascript', 999);
